17 Claims.

My invention relates to pattern yarn feeding mechanism for circularknitting machines and it is an object thereof to provide improved meansfor making vertical stripes in the fabric produced thereon, as well asother patterns and embroidery effects. This machine is of the type inwhich the patterning Iis produced by introduction of a separate extrayarn at each point where the pattern is desired. 'I'he selection of theneedles around which the pattern yarns are to be laid can beaccomplished by raising the selected needles to a higher level than theothers, as usual. The patterning yarns are supplied from yarn guideswhich pass the yarns across the needle circle from inside to out andback again.

Referring to the drawings, which are made a part of this application andin which similar reference characters indicate similar parts:

Fig. 1 is an elevation, partly in section, showing part of a circularknitting machine with my invention applied thereto,

Fig. 2 is a horizontal sectional view of the machine of Fig. 1 taken ona line through the feeding ends of the pattern yarn fingers, certainparts being omitted to show others more clearly,

Fig. 3, a detail illustrating the method of supplying the pattern yarnto the needles,

Fig. 4, a detail showing a plan of a cam,

Figs. 5 and 6, detail elevations of modified forms of yarn fingers, and

Fig. 7, an elevation of a needle and jack.

In the drawings, reference character I0 indicates a needle cylinderrotating in a clockwise direction as the machine is shown in Fig. 2, andhaving needles Il in its slots as usual, which needles are elevated anddepressed by conventional needle knitting cams (not shown). In additionto such needle cams I provide special cams I2, one for each point whereneedles are to be specially elevated, these cams being mounted on stemsI3 movable radially in bearings il by suitable pattern mechanism. JacksIla are located in the needle slots underneath all the needles, or onlybelow certain ones if preferred. 45 The jacks have butts lib coactingwith the above mentioned conventional needle raising and lowering camsof any desirable or conventional character for causing the knitting. Thejacks also have patterning butts ile and lid at different levels forcoacting with the special elevating cams l2. As indicated the patterningbutts are of different lengths and they may vary widely in each series,so as to raise needles in varying numbers and in varying sequencesaccording to the positions of the special lifting cams I2 (only one ofwhich is shown in the drawings). In practice it has been found thatjacks with upper butts of six different lengths and lower butts of sixdilerent lengths can be used with two of the special raising cams l!described and that such jacks work in satisfactory manner. Obviouslythis enables me to make a great variety oi' patterns in the fabric. Forexample, a long butt jack can be arranged at the middle of a group ofseveral jacks with shorter butts whereby in one position of cam I2 onlythat needle is raised which is above the long butt jack and in anotherposition both the long butt jack and the medium butt jacks raise theirneedles into yarn taking position. Many other arrangements will suggestthemselves to those skilled in the art.

The machine is supplied with a sinker ring I5. a. latch ring it, one ormere main yarn guides l1 and operating means for said guides includinglevers I8, all of which may be of any conventional or desirablecharacter. By the term main yarn as here used I intend to designate anyyarn which may be used in the body of a stocking or in any part thereof,e. g., one of several yarns for making horizontal stripes, splicingyarns or some other yarn or yarns not intended for my special yarnfingers hereinafter described, one such main yarn being indicated at I9.

For the purpose of permitting the striping or patterning yarn to enterthe selected needles only and to prevent it entering the needles notselected, a guard 20 is mounted inside the needle circle. 'Ihis guard isshown as a segmental ring or apron beginning shortly after the knockingover point and ending at point 3| just prior to the knocking over point.The upper edge of this ring is formed as a cam of which certain partsare high to lift a pattern yarn or yarns above the needles not speciallyelevated at that point to take such pattern yarn or yarns. This ring orapron is supported by a bracket 2| (Fig. 1) secured to a block 22mounted on the latch ring or other suitable support. This ring or apronforms the subject-matter of certain claims in my co-pending applicationSerial No. 707,976, filed January 23, 1934, now Patent No. 2,019,940,dated November 5, 1935. Attention is also called to my Patent No.2,025,913, dated December 31, 1935, claiming certain othersubject-matter disclosed in this application, said patent being adivision of the present application.

A specially formed separator 30 is secured to or formed integral withblock 2l and extends around past the ending point 3l of the segmentalring orapron 20 thereby preventing interference between the patternyarns and the main yarns or the guides therefor at the point where themain yarns are fed to the needles (see Fig. 1). A main yarn such as thatindicated at I9, when put out of action, is cut off by a yarn trap (notshown) which is located at the left hand side of bracket 2| (shown inFig. 2) and which forms no part of' my invention herein claimed. Theleading end of the separator is spaced some distance radially inwardfrom the end 3| of the segmental ring 20. 'Ihe pattern yarns slideinside the lower inclined edge of the separator after they pass thepoint where they are taken by the needles and are held in idle positionwithin the circle of needles.

One of the principal features of my invention is an element or abutment24 extending across the needle circle at a distance from the main yarnfeeding means and adapted to carry a pattern yarn into contact with theselected needles as the relative rotation between the needles and theabutment 24 takes place. Specifically the abutments 24 are shown asstationary and a pair of circumferentially adjustable blocks 23 held byscrews 23' engaging horizontal slots in said blocks serve to supportabutments 24 extending radially over the needle circle and each having ahook at its end providing a space through which specially elevatedneedles move as indicated in Figs. 1 and 3, in taking a pattern yarn.The other needles remain approximately at the level indicated at theleft hand side of Fig. 3. The abutments 24 have slots at 25 to receivescrews 26 whereby the abutments are attached to the blocks 23 withcapacity for radial adjustment so that the recess or gateway for thehooks of the needles will be properly positioned to permit the needlesto pass midway of the width of the recess and to prevent itV fromstriking the abutment if it should be bent slightly at its upper end.The downwardly bent outer ends of the hook shaped portions of abutments24 have inclined faces as indicated at 21 to cause the yarn to slidedown past the abutments without being hung up or broken thereby.Preferably the blocks 22 and 23 are supported. on

` the latch ring so that the blocks and the parts carried thereby willbe out of the way when the latch ring is swung back about its pivot 20.

The means for laying the pattern yarns in the path of the abutments andthe specially elevated needles comprises one or more yarn fingers hereshown as arranged in closely-adjacent pairs 33, 33 having at their upperends hooks 34' by means of which they are held between two rotatingplates 34 and 35 fixed to a hollow sleeve 3B which is supported on aflange 31 of a sleeve 38 carried by a bracket 39 secured to the fixedframework of the machine in any suitable manner. A horizontal drivenshaft 40 of the machine drives sleeve 36 through bevel gears 4l and 42.The shaft 43 is driven from a shaft 4l' through bevel gearing 4I". Theshaft 4I' is in two sections adapted to be connected by a clutch 42through the medium of a lever 43" operated by any suitable patternmechanism to throw out the clutch at the'time when the needle cylinderstarts to reciprocate for making heels and toes, at which time thepattern yarn fingers are not operated but are held in idle position bysprings hereinafter described. The shaft 4I' is driven from a constantlyrotating shaft of the machine through suitable connections indicated at43" (Fig. 1).

The pattern yarn fingers are guided for radial movement by means of aslotted ring forming guides and supported on said sleeve 36, the guidesbeing indicated at 43. An open ring 44 having inwardly facing guidingslots for the lower ends of the fingers has passages at 45 for thepattern yarns 46 which are led through these passages and then to theeyes 41 at the lower ends of the yarn fingers.` The ring 44 is supportedby arms 44' depending from a bobbin stand (not shown) arranged betweenthe plate 35 and the gear 42, it being understood that the gear 42 is ata considerable distance above plate 35. Each pattern `yarn finger isdrawn toward idle position by means of an individual coil spring 48',such coil spring being connected to its finger in any suitable manner,as by means of a hook encircling the pattern yarn finger and beingconnected at 4its inner end to a suitable part such as a. ring 43"surrounding a collar 43 which forms part of the fixed frame of themachine. A precautionary spring ring 48 serves to hold the yarn ngersaway from abutments 24 in case of failure of one of the springs 48'. Itis to be noted that these yarn fingers have a radial movement onlyrelatively to the needles, i. e., they do not move about a needle orgroup of needles in laying a. `pattern yarn around the same, theiraction being supplemented by abutments 24 for this purpose.Circumferentially the yarn fingers are each just in advance of the groupof needles around which its yarns can be-wrapped.

The pattern yarn fingers are provided near the middle of their lengthwith butts or projections 50 which serve as followers for cams 5l and52, such cams being arranged in any suitable number on a shaft 53passing upward through sleeve 3B and being secured thereto by set-screws53 or the like to permit adjustment of the cams about the shaft. Theshaft 53 is pivotally connected at its upper end to a lever 53 by meansof a collar 6U and a yoke indicated at 6|. This lever 53 is pivotedintermediate its ends to the fixed bracket 33. The lever 53 has afollower 62 at the opposite end of the lever from the collar $0 restingon a cam surface 63 on a pattern element 64 'pivoted at 65 to thebracket 39 and having pivotally connected thereto a rod 6E operated by apattern chain or pattern drum to move the cam 64 about its axis and socause the lever 59 to swing on its pivot, thereby raising or loweringshaft 53 and its cams 5I and 52 so as to vary the operation of thepattern yarn fingers due to the fact that dierent followers on the yarnfingers will be engaged by the cams at their various elevations.

It is desirable to move the special yarn flngers outward into theneighborhood of the needle circle before they are actually caused tocross the needle circle by their respective cams 5I and 52. For thispurpose I have provided at a point above the cam 52 a support 61 (Figs.1 and 4). This support comprises a cylindrical portion with threadedholes at 61 for set-screws to hold it on shaft 53 and an overhangingflange, as shown in Fig. 1. A plate 68 is secured to the support 61 bymeans oi' aclamping screw 69 passing through a slot 10, said platehaving an outwardly projecting cam portion 1| (Fig. 4). This plate is soarranged as to give a preliminary'outward movement to a pattern yarnfinger which is to be engaged and moved fully out by plate 5I. If theplate were not provided the finger would be thrown out with undue speedand suddenness from which damage to the mechanism or an imperfectpattern in the fabric might result. Another cam plate having a vcam 12is secured to the support 61 in proper relation for pre-advanc- I3 lngpattern yarn fingers which are to be enaaged and operated by cam I2.After the lingers have passed the respective pre-advancing and mainactuating cams they are pulled back suddenly to idle position byindividual springs 4l'.

The butts or followers Il on each pattern nger are shown in the drawingsas spaced from each other a distance at least equal to the width of afollower and in Fig. 1 each follower on one linger of the pair isstaggered with relation to the same follower of the other linger. Inaddition the followers are shown with a gap 14 between each suchstaggered pair of followers. In Fig. 1 each pattern yarn finger is shownas having two pairs of followers and the other finger of the pair hasfollowers lying opposite the spaces in that first named finger, so thataccording to the up and down adjustment of the cams 5l and 52 such camswill either engage followers on one of the pattern yarn fingers of apair or on the other according to the desired pattern, unless the shaft53 is elevated or depressed to such an extent as to bring the upper camabove the plane of all the followers or to bring the lower cam below theplane of all the followers and the other cam opposite gap 14.

In Fig. 2 there are shown ten pairs of pattern yarn ngers and by meansof these fingers patterns can be made at ten or more intervals about astocking or the like, which patterns may of course be interrupted asdesired so as to form interrupted stripes or mere spots or any otherdesired designs. 'I'he width of a rvfigure may be varied bycircumferential adjustment of blocks 23 or cams 5I and 52, by changingthe Varrangement of the various sized butts on the jacks, or by movingthe special jack cams inward to a greater or less extent according totheir pattern control, thereby changing the number of needles to bespecially elevated according to the pattern desired. By having thefingers arranged in pairsa finger 33 may for example control a whiteyarn and a finger 33' may control a red yarn. If now the body of thestocking be of some other color, a pattern may be produced consistingalternately of red yarn and white yarn. As the pattern yarns supplied tospecially elevated needles can' be changed at any rotation of themachine such changes may take place as often as desired, and the numberof colors following each other in the same wales can also be increasedby increasing the number of closely-adjacent pattern yarn iingers. It isnot desirable that the patterns should continue through the heel or toeof a stocking and usually they are not desired in the sole of the foot.In knitting heels and toes by reciprocation, as usual, or in plainknitting where no patterns are desired, the pattern mechanism moves thecam plate 54 counter-clockwise to a point where the roller 62 engagesthe low part at 13 of the cam surface 53, whereby cam 52 will pass abovethe uppermost follower on each pattern yarn nger and cam 5I will passthrough the space between the upper and lower pairs of said followers,which is widened for this purpose as indicated at 14 in Fig. 1. For thereason set forth none of the pattern yarn fingers will be oscillatedradially and no patterns w'll be made thereby. It should be noted thatthe oscillating cam plate 64 has ve positions for roller 62,corresponding to the necessary number of positions of cams 5I and 52 foroperating or idling the pattern yarn ngers. It is within the bounds ofmy invention to group more than two pattern yarn fingers at each patternposition. Also a larger number of steps may be provided on oscillatingcam plate 44 and the arrangement of followers on the pattern yarnfingers may be correspondingly varied, e. g., by providing three pairsof followers each nnger, etc.

For knittingg'a stocking with patterns in the leg and instep but not inthe heel, toe or sole, pattern yarn-fingers such as shown in Fig. 5 areused in the section of the needle circle corresponding to the heel, toeand sole. It will be seen that the upper pair of followers 1I is thesame as the upper pair of followers on the correspondlng ilngers of thepairs shown in Fig. 1, while the followers 18 are the same as the lowerpair on corresponding fingers of the pairs shown in Fig. 1., 'I'he cams5I and 52 being positioned either at a low point as indicated at theleft hand of Fig. 5 or at a high point as indicated at the right of saidfigure, the two pattern yarn ngers as shown in Fig. 5 and all similarpattern yarn lingers in the heel section will not be operated by thecams 5| and 52 but the operation of the instep pattern yarn fingers likethose in Fig. 1 may be continued. This makes a sole without pattern. butpatterns may be placed in the sole if desired, leaving the Vheel and toeplain; merely by unclutching the clutch 42' during. the knitting of theheel and toe.

In Fig. 6 I have shown a pattern yarn finger having only two followers11 instead of two pairs of followers with a space between them as shownin Fig. 1. Such a pattern yarn nger may be used where a one-colorpattern is to be made throughout the length of the stocking, theadvantage of this linger being that it is cheaper to make and the singlefollower wears longer and is less liable to be bent or damaged than thenarrower followers of a pair on the ngers in other figures.

' In the operation of forming a pattern according to the disclosure ofFigs. l to 4 it will be seen that as the needles', the pattern yarnfingers and the bobbln stand rotate, a selected pattern yarn finger willrst be moved radially by its preadvancing cam and then by either one ofcams 5l and 52 so as to lay its yarn between a. specially elevatedneedle or needles and the hooked end of abutment 24. A needle or a groupof needles being elevated into position to pass through the recess insaid hook portion of abutment 24, the first of such needles will strikeagainst thc yarn which is held in proper position by the hook, and thepattern yarn is carried on through said hook by such needles.Immediately thereafter the cam 5| or 52 releases the pattern yarn finger33 which retilrns to its position near the center of the needle circleand the rearmost portion of the bight of yarn laid about the needle orneedles will slide over the abutment 24 and down the incline 21 and beheld by the retracted needle in the position indicated in connectionwith the needle in Fig. 3.

'I'he broad claims to the abutment and the method of operating themachine containing the abutment to produce a wrap stripe, are in mydivisional Patent #2,025,913 above referred to.

It will be obvious to those skilled in the art that variousmodifications may be made in my device without departing from the spiritof the invention andtherefore I do not limit myself to what is shown inthe drawings and described in the specification but only as indicated inthe appended claims. It will be obvious also that patterns of manyvarieties may be made. As one example of such pattern a stripe may bemade in one color said stripe being interrupted at intervals by widerspots of a different color, the yarn for said spots being provided byone of two juxtaposed pattern yarn fingers and the yarn for the balanceof the stripe by the other. 'I'his is merely one illustration of apossible pattern as it will be obvious to those skilled in the art thatmany other patterns may be made by varying the position of the cams 5I,52, the lengths of jack butts, the position of cams l2, etc. Thus, forexample, by juxtaposing three or more pattern yarn ngers a narrow stripemay show several colors in succes-- sion.
